las vegas reaching to 118. >> you've been reporting on this heat dome in place for a good 48 hours now. you were telling me earlier this system is really sort of locked in place. >> you know, i'd love to tell you this breaks in the next day, but it doesn't. that's the problem. it compounds. that's how people get sick. look at the numbers. the next three days, look at las vegas. we see temperatures, 118, through the start of the work week. phoenix at 112 monday. death valley will get to a cool 127 by the mid week. so we will eventually see breaking of this heat dome, but not until after the holiday for some. >> too bad not until after the holiday. ginger, thank you. the other major weather headline this evening coming to us out of indianapolis, where three children were struck by lightning at a summer camp. the fire department reporting one of the children is in critical condition this evening. camp counselors had begun life-saving efforts and took the children to the hospital. comes days after the boy scouts,

protesters, opposed to his administration's policies on terrorism, including the use of drone strikes, but he received an enthusiastic welcome at a town hall with young leaders. at every stop in africa, president obama has paid tribute to mandela. >> the outpouring of love that we've seen in recent days shows that the triumph of nelson mandela and this nation speaks to something very deep in the human spirit. >> reporter: obama's met mandela only once and for just ten minutes as a junior senator. two years ago, michelle obama and daughters sasha and malia had a chance to meet with him. afterwards mrs. ob -- obama told david muir it was the opportunity of a lifetime. >> what did you say to him? >> i told him, you cannot imagine how important your legacy is to who i am, to who my husband is. i just said thank you, thank you, thank you. >> it was expected to be the

emotional high point of the president's trip to africa. the obama family will go to the infamous prison on south africa's robben island tomorrow to see the cell where nelson mandela spent 18 years of his 27 years in prison. david? >> robben island just off cape town there. jon, that you. now to another phone call tonight the one a mother and father received about their son studying abroad. he was teaching children english abroad when he was stabbed and killed by a protester as a tense demonstration unfolded in egypt. abc's susan saulny reports. >> reporter: he had gone to alexandria, egypt, for the summer to teach english and sharpen his arabic. a budding scholar on the middle east. andrew pochter was 21, he would have been a junior this fall in ohio. he left home in maryland to work in pursuit of peace. but he found violence instead. riots between opponents and
